Specification of Letters Patent.

Application filed .Tul5T 21, 1910. Serial No. 572,971.

To all Awhom. 'Lt may concern:

Be it known that I, ANDREW W. BRITTER, a citizen of the United States, residing` at Abilene, in the county of Taylorand State of Texas, have invented certain new and useful Improvements in Quilting-Wachines, of which the following is a specification.

My invention relates to new and useful improvements in quilting machines. lts object is to provide a machine equipped with a plurality of vertically reciprocating needles and horizontally reciprocatingshuttles in conjunction with a take up and a feed mechanism adapted to stitch said quilt by feeding the same once through the machine.

A further object is to provide novel and efficient mechanisms for operating the needles, shuttles, take up and feed.

Finally the object of the invention is to provide a device of the character` described that will be strong and durable and comparatively simple in construction, and one, the various parts of which, will not be likely to get out of working order.

With these and various other objects in view, my invention has relation to certain novel features of operation and construction an example of which is described in the following specification and illustrated in the accompanying drawing, wherein:

Figure 1 is a plan view of the quilting machine. Fig. 2 is a front view thereof. Fig. 3 is a vertical sectional view taken on the line X-X of Fig. 1. Fig. 4 is a vertical sectional view taken on the line 3/-3/ of Fig. 2. Fig. 5 is an end view of the machine, the main driving shaft and its supporting brackets being broken-away.

Referring now more particularly to the drawing, wherein like numerals of reference designate similar parts in all the tigures, the numeral 1 denotes the feed table upon which the quilt will be fed to the machine. Beneath this table and spaced therefrom is positioned a bed-plate 2 upon which operate the reciprocating shuttles. Above the table 1 are provided two shelves 8 and 4 spaced from said table and from each other and supported at each end by vertical walls 5. A plurality of rods G, adapted to undergo a vertical reciprocating motion are mounted in the shelves 3 and 4, said rods being equidistant and horizontally alined. Each of these rods carries an eye-pointed needle 7 upon its lower extremity, and an aperture 8 through which said needle is adapted to pass is positioned in the work. table 1 directly beneath each needle. The rods G are rigidly connected by a clamping bar 9 causing them to reciprocate in unison. Each of the two outside rods is acted upon by a connecting rod 10, and the connecting rods are each operated by an eccentric 11 mounted upon the shaft 12. rllhe extremities of this shaft are supported in brackets 13 mounted upon the upper shelf 4. A thread 14 passes through the eye of each needle each thread being wound upon aspool 15 mounted upon a pin 1G projecting vertically from the shelf 4. Each thread passes around a' pair of tension disks 17 which regulate the strain upon the thread as it is gradually drawn off of the spool through the operation of the needles. The take up consists of a plurality of hooks 18 through each of which one of the threads 14 is passed, said hooks being mounted upon an oscillating bar 19. This bar is supported at each extremity by levers 20 mounted upon pivots 21. rlthe inner extremities of each of these levers carries a pin 22 to which an oscillating motion is communicated by a cam 23 provided with a groove 24 in which said pin works. The cams 28 are each mounted upon a shaft 25 from one of which shafts rotation is communicated to the eccentric shaft 12 by a pair of pulleys 26 and a belt 27.

A frame is provided to receive the fabric to he sewed, consisting of a pair of bars 28 slidably mounted in grooves in the table 1, and provided with upturned arms 29. At each end of this frame two rods 30 and 31 are mounted in the arms 29 and upon each of the upper rods 81 is mounted a ratchet wheel 32 acted upon by a spring pawl 33. The extremities of the fabric are wound upon the rods 31 after having been passed under the rods 30 in order to cause the fabric to lie fiat upon the table. A pawl and ratchet mechanism prevents reverse rotation of the rollers which carry the extremities of the cloth so that the fabric is stretched tight while being sewed. A shuttle 34 mounted in a carriage 35 is adapted to reciprocate upon the bed-plate 2 beneath each of the apertures 8, said shuttle having a stroke of sufficient length to carry it from one side of the aperture to the other. Each of the carriages 35 is rigidly connected by a rod 36 with a transverse bar 37, and a reciprocating motion is imparted to said bar through a pair of connecting rods 38 and eccentrics 39. The eccentrics are mounted upon a shaft 40 supported at its extremities in brackets 4l. The shaft 40 serves as a driving shaft for the other mechanisms of the machine, a pulley 42 being mounted upon said shaft through which rotation may be communicated thereto.

The cam shafts 25 are operated from the shaft 40 through pulleys 43 and belts 44. The fabric being sewed receives its feed motion after each stitch from a number of feed plates 45, one of which is mounted in the surface of the table l adjacent to each of the needles. These feed plates are carried upon the upper extremities of arms 46 rigidly secured to oscillating levers 47. One extremity of each of these levers is connected withan eccentric 48 carried by a shaft 49, and the other extremity of each lever is provided with a slot 50 receiving a stationary rod 5l. Rotation is communicated to the shaft 49 from the shaft 4() through a pair of pulleys 52 and a belt 53. Upon each of the feed plates there rests a bifurcated foot 54 carried in the usual manner at the lower extremity of a rod 55, to which a downward pressure is communicated by a spring 56. The feet 54 serve to hold the fabric securely down upon the work table and upon the feed plates 45. The feed plates are provided with serrated surfaces in order that the cloth will be carried forward by the forward motion of the plate but will not be affected by the rearward motion of said plate. The shuttles employed may be of any suitable and well known construction.

It is obvious that any number of needles may be used to give the required number of stitches.

Vhat I claim is:

In a quilting machine, the combination with a table containing a plurality of alined apertures, of a vertically reciprocating eyepointed needle mounted above each aperture, means establishing a rigid connection between all of the needles, eccentrics by which a reciprocating motion is imparted to the gang of needles, a horizontal reciprocatn ing' shuttle mounted beneath each of said apertures in the table, eccentrics by which a reciprocating motion is communicated to the shuttle, a serrated feed plate adjacent to each needle, an upright arm carrying each of said feed plates on its upper extremity, an oscillating bar upon which each of the arms is rigidly mounted, a spring pressed bifurcated foot Arest-ing upon each of said feed plates, a grooved cam mounted at each extremity of the quilting machine, a pair of pivotally mounted levers, one of the extremities of each of which is adapted to be trans versely oscillated by one of said cams, a bar connect-ing each of the two extremities of the levers, and means carried by said bar engaging each of the threads, passing through said needles.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
